Answer:

x = 4\frac{2}{3}      y = 7        and    z =3\frac{1}{3}

This implies the equation has just one solution

Step-by-step explanation:

To create the equation, we need to be able to write the information  or interpret the question mathematically.

Let x equal to the number of red balls.

Let y equal to the number of blue balls.

Let z equal to the number of green balls.

From the question; "The number of red balls is 2/3 the number of blue balls" can be mathematically written as :  x = \frac{2}{3} y  ---------------------------(1)

The next statement; "The number of green balls is 1 more than 1/3 the number of blue balls" can be written mathematically as: z = 1+\frac{1}{3} y ----------------------------(2)

The next statement; "she has 15 balls."  can be mathematically written as:     x + y + z = 15 ----------------------------------------(3)

Substitute  equation (1) and equation (2) into equation (3)

\frac{2}{3} y + y +1 +\frac{1}{3} y  =  15

We can rearrange this equation

\frac{2}{3} y  +\frac{1}{3} y + y +1 =  15

\frac{3}{3} y  + y + 1 = 15

y + y + 1 = 15

2y + 1 = 15

subtract 1 from both-side of the equation

2y + 1 -1 = 15 -1

2y = 14

Divide both-side of the equation by 2

2y/2 = 14/2

y = 7

Substitute y = 7 into equation (1)

x = \frac{2}{3} y

x = \frac{2}{3} (7)

x = 14/3

x = 4\frac{2}{3}

Substitute y= 7 in equation (2)

z = 1+\frac{1}{3} y

z = 1+\frac{1}{3} (7)

z = 1+ 7/3

z = 10/3

z =3\frac{1}{3}

Therefore;

x = 4\frac{2}{3}      y = 7        and    z =3\frac{1}{3}

This implies the equation has just one solution.

15. If R is the midpoint of OS, OR = 8x - 51 and RS = 3x - 6, find QS.
Vikki [24]

Answer:

if you mean find OS, then:

OS = 42

Step-by-step explanation:

if you mean find OS, then:

8x-51 = 3x-6

5x = 45

x = 9

OS = 2(3x-6)

OS = 6x-12

substitute for x

OS = 6(9)-12 =42

How many vertical asymptotes exist for this function?
marin [14]
Remember that to find the vertical asymptotes of rational functions, we just need to set the denominator equal to zero and solve for the variable, in this case x, so lets do it:
(x-4)(x+1)=0
x=4,x=-1

As you can see, our rational functions has 2 vertical asymptotes: x=4 and x=-1
